What are the methods to eliminate car noise?
2 Answers
Eliminating car noise can be achieved through the following methods: 1. Apply butter or specialized lubricating oil at the connection between the brake pads and brake calipers; 2. Disassemble and inspect the bearings, clean them, apply lubricating grease, and then reassemble the bearings and brackets; 3. Remove the fan blades to apply lubricating oil and clear any foreign objects; 4. Check the working condition of the engine and transmission. The causes of car noise include: 1. Slippage of the flywheel ring gear; 2. Poor quality of gasoline; 3. Excessive wear of brake discs and brake pads; 4. Abnormal brake calipers or lack of brake fluid; 5. Loss or imbalance of the dynamic balance weights on the drive shaft; 6. Tension or damage of the air conditioning compressor belt and tensioner pulley; 7. Engine wear or improper assembly and adjustment.
I've been driving for over a decade and have figured out many DIY methods to eliminate strange noises. For example, if the car door squeaks, it's mostly due to aging door hinges or lack of lubrication—I simply spray some WD-40 lubricant, and the effect is immediate. As for noises near the tires, it might be small stones stuck in the treads; just pick them out with a screwdriver. The sharp sound from worn brake pads requires checking the brake system—measure the thickness yourself and replace them if they're too thin. More troublesome issues involve the suspension, like leaking shock absorbers causing creaking sounds when driving over bumps, which requires consulting a knowledgeable friend or visiting a repair shop. One extra note: ignoring these minor issues for too long not only becomes annoying but also affects driving safety, especially when sudden noises on the highway can distract you. So, I always start by testing the source of the noise with simple methods, and if I can't fix it, I promptly seek professional help—don't delay until it becomes a major issue that costs more to repair.
